{"cve":"CVE-2026-45062","nvd":{"published":"2026-06-10T18:16:57.077","modified":"2026-10-25T23:10:00.167","status":"Deferred","description":"FrankenPHP is a modern application server for PHP. From version 1.11.2 to before version 1.12.3, the splitPos() function in cgi.go misuses golang.org/x/text/search with search.IgnoreCase when the request path contains a non-ASCII byte. Two distinct flaws in that fallback let an attacker mislead FrankenPHP into treating a non-.php file as a .php script. In any deployment where the attacker can place content into a file served by FrankenPHP (uploads, file storage, etc.), this can be escalated to remote code execution by crafting a URL whose path triggers either flaw. This issue has been patched in version 1.12.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1},"cwes":["CWE-20","CWE-176","CWE-178"],"references":["https://github.com/php/frankenphp/releases/tag/v1.12.3","https://github.com/php/frankenphp/security/advisories/GHSA-3g8v-8r37-cgjm","https://github.com/php/frankenphp/security/advisories/GHSA-3g8v-8r37-cgjm"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-45062","score":0.00714,"percentile":0.53424,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-3g8v-8r37-cgjm","url":"https://osv.dev/vulnerability/GHSA-3g8v-8r37-cgjm","summary":"FrankenPHP: Unsafe Unicode Handling in CGI Path Splitting Allows Execution of Non-PHP Files","modified":"2026-06-25T18:56:26.357114831Z","packages":[{"ecosystem":"Go","name":"github.com/dunglas/frankenphp","purl":"pkg:golang/github.com/dunglas/frankenphp","ranges":[">=1.11.2 <1.12.3"],"fixed":["1.12.3"]}]},{"id":"GO-2026-5084","url":"https://osv.dev/vulnerability/GO-2026-5084","summary":"FrankenPHP: Unsafe Unicode Handling in CGI Path Splitting Allows Execution of Non-PHP Files in github.com/dunglas/frankenphp","modified":"2026-06-25T18:45:17.776165577Z","packages":[{"ecosystem":"Go","name":"github.com/dunglas/frankenphp","purl":"pkg:golang/github.com/dunglas/frankenphp","ranges":[">=1.11.2 <1.12.3"],"fixed":["1.12.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
